When the spacecraft came to the most central area of the asteroid belt, a huge spacefortress appeared in front of it, and from time to time ships came in and out.

Except for Ye Quan, Ye Mingchang and the others were stunned, even if they had been to the "Crystal Palace" undersea base before, they couldn't compare it to this time.

Last year, Ye Quan exchanged for a third-level civilization space fortress, 400 mining ships, and a batch of robots, spending nearly 200 million psionic points.

With a saucer-shaped diameter of over 15 kilometers and a height of over 4 kilometers, Battlestar is a huge manufacturing base for the production of various ships and robots.

Compared with space battleships, Battlestar focuses on defense, but also has powerful attack capabilities, and Ye Quan named it "Dragon" very uncreatively.

The Dragon Battlestar combines military, mining, and manufacturing functions, and is the first space base in the Yequan Space Program.

Its mission is to carry out surveys and exploration of minerals around the solar system and to exploit the mineral resources of the asteroid belt.

In addition, an asteroid with a diameter of more than 22 kilometers has been hollowed out next to it, and it houses a refining plant for various minerals.

To put it simply, Ye Quan regarded the "Dragon" as a hen, growing through a steady stream of eggs.

There is not a single living person in Battlestar, and all processes such as mining, refining, manufacturing, and assembly use intelligent robots.

If everything is revealed, people will be horrified to find that the robots here are making robots, and this cycle is like a prelude to the destruction of the world in the movie novel.

It is also the day and night efforts of countless robots that have taken place in less than a year. It was built on such a huge scale. After the discovery of the Yellow Star. In another six months, three spaceships and more than a dozen semi-finished products were built.

However, the robots that came forward to entertain Ye Mingchang and others were all disguised on the surface and looked no different from ordinary people.

Seeing the huge hull in the space dock, Ye Mingchang came back from the shock and said with a wry smile: "If you weren't my son, you've been by your side for the past few years." I'd definitely suspect you're an alien or something. ”

Ye Quan felt the need to disclose some insider information to his parents and others, and said: "A few years ago, I got a great opportunity, and I mastered a lot of technology beyond the times.

"This mining and manufacturing base is nothing, in my space program, it includes a space city, a moon base, a Mars base, a space mining base, a solar system defense circle and an interstellar fleet.

"Last year, an expedition spacecraft discovered a huge planet of life 157 light-years away. Its planet is 26 times the size of the Earth and is named Yanhuang Star. By the end of next year at the latest. This news will be made public to the public, and the great migration of mankind will begin. Times are different, and my goal is not on the earth, but on the sea of stars.

"I'm here to see off the First Starfleet, and they will be the first batch of pioneers to establish a colony on Yanhuang Star."

Ye Mingchang, Cao Shuyun, Han Yueying and Ye Ting glanced at each other, as if in a dream, and didn't know what to say.

According to the news sent back by the cyborgs on the No. 9 spacecraft, the gravity of Yanhuang Star is 1.21 times that of the Earth, one day and night is equal to 5.6 days of the Earth, and the average aura concentration is 33%, and in some places it even exceeds 50%.

The most important point is that the composition of the atmosphere of Yanhuang Star is about the same as that of Earth, and the oxygen content is slightly higher.

If the earthlings do not wear breathing apparatus, they will have drunken oxygen reaction, fatigue, weakness, drowsiness, chest tightness, dizziness, diarrhea and other symptoms, and even serious adverse consequences.

However, according to the test, it has been shown that people who have strengthened above level 1 or have been injected with genetic immunity can survive well on Yanhuang without any protective equipment.

And their descendants born on Yanhuang can also inherit this, fully adapted to the atmosphere and gravity environment, which is the basis for large-scale migration.

Such a living planet hardly requires much artificial modification, and it is simply the best gift from God to mankind.

There are no intelligent civilization races on Yanhuang Star, but some beasts have extremely high intelligence and strong strength, and even beasts that can fight against those who are above level 8 strengthened, and these dangerous creatures are collectively called "super species".

The ground research team sent by the No. 9 spacecraft has suffered several attacks and even casualties, and now can only use satellites and high-altitude reconnaissance vehicles to observe the surface of the planet.

Ye Quan knew that this was because of the large concentration of spiritual energy on the Yanhuang Star, and there would definitely be a "spirit beast" appearing.

Spirit beasts can absorb spiritual energy, have a strong physical body, a long lifespan, and a high IQ, and some have also controlled the use of some spiritual energy.

According to the division of the space system, spirit beasts are also divided into one to nine orders, but the levels are not completely differentiated according to strength.

There is also the existence of "Starry Sky Beast" above the ninth-order spirit beasts, which are beasts that surpass the Heavenly and Human Realm and SSS-level powerhouses, which are equivalent to the planetary, stellar, and galaxy levels in human legends, and many adult starry sky beasts have the terrifying strength to easily destroy a planet.

However, if it can fight against an eighth-level or above strengthener, then it is at least an eighth-order spirit beast, and its strength definitely surpasses that of Jindan Grandmaster and ordinary S-level powerhouses.

The orcs are also a large civilization race in the universe, and their way of promoting civilization is completely different from that of humans, except that the number of each species is pitiful, but the individual strength is much stronger than that of humans of the same level.

Because the preparation time was too short, the "Dragon" spacestar only stepped up to complete three spaceships, an interstellar cruiser "Voyage", a landing ship and a medium-sized transport ship, the so-called "First Starfleet" was formed from these three spaceships.

The cruiser "Yuanhang" is 1,580 meters long, 260 meters wide and 215 meters high, and its power system, protection system and main gun are the fourth-level civilization equipment produced by the universal base.

This allows the Voyage to have an energy shield, three electromagnetic railcannons, twelve ion cannons, and other weapons systems.

The same goes for the transport spacecraft and the landing spacecraft, both of which are quasi-fourth-level civilization levels, with a maximum speed of only 8 levels of warp speed, and it takes more than five months to reach Yanhuang Star.

On the contrary, the twelve scientific exploration spaceships exchanged by Ye Quan really have the level of a fifth-level civilization, and it only takes a few days to go back and forth. Unfortunately, although this kind of expedition spacecraft is all-powerful, it cannot carry more people and no more goods, and it also has interstellar exploration missions.

In fact, the manufacture of a large fourth-class civilization warship requires too many rare elements, and if it were not for the exchange system with space, it would be difficult to create one even if humans completely occupied the solar system in the future.

Only a civilization that rushes out of the solar system, travels at more than 100 times the speed of light, occupies resources in a star field within a range of hundreds of thousands of light years, and begins to colonize other planets on a large scale can enter the ranks of fourth-level civilizations, so as to create large warships that represent the highest level of civilization.
